Simple tool to configure Windows Filtering Platform (WFP) which can configure network activity on your computer. The lightweight application is less than a megabyte, and it is compatible with Windows Vista and higher operating systems. You can download either the installer or portable version. For correct working, need administrator rights. Features: - Simple interface without annoying pop ups. - Rules editor (create your own rules).
- I may not be exactly, or as good as GlassWire, but as a lightweight, free and open-source alternative it definitely provides a very decent and totally unbiased firewall, giving maximum protection to the end-user over which apps and services have access to the open internet.
- It's free, doesn't nag you, and gives you a similar level of control.
